The Gun Thread

Reviving this almost dormant thread....
I just got a new tool for my load testing.... I've used regular chronographs for velocity measurements when working up loads... this is relatively new to chronographs.... it's an actual doppler technology radar unit. It's supposed to be quite a bit more accurate/consistent than the conventional types.
The best part is that you set it on your bench without having to set anything up downrange. Use it for 10 shots, then stop it. Start it back up later if you wish, without having to wait for a range cease-fire.... (plus it's cool looking )
I plan to try it out in the next few days.... this pic is what it looks like.... just a generic web pic... I'm much better looking than that guy in the pic...

Nosy question that is really none of my business and you can tell me to mind it if you want to.

How much did that gizmo set you back?

this is what the conventional chrono's look like. You mount them on a tripod, and set them out in front of the shooting bench, about 10-15 feet away. You have to align it with your line of fire and the target, so that you shoot across the top of it, lengthwise, through the skyscreens.
It's not difficult to do, but it takes about 4 or 5 minutes, depending on how lucky you get when aligning it.. minimizes the walking back and forth.. other shooters that are waiting for the line to go "hot" again sometimes get a little antsy....
Also, it is fairly common for people to forget that the line of bullet travel is a couple of inches below the line of sight... when they try to shoot too low over the sensors, they end up perforating the chronograph... that usually makes them not work too well anymore...

"Found" one of these at the last gun show, looks nearly new, it is a war years model with the plastic grips, was bone dry, gave the mobil 1 lube treatment, runs great-

So the method you had before worked about the same way as how I checked the top speed of my new electric bicycle a couple weeks ago. Two mile markers and a stopwatch. And your new one works more like a radar gun.

I'm trying to work up a good load in my new-to-me Ruger SFAR... a smaller frame AR in .308. Full .308 goodness out of an AR-15 size (and weight) platform. Good stuff.
Also, an AR-15 in 6.5 Grendel. It's a really neat little cartridge, with a little more power than the 5.56mm.... this one should be great on deer/hog size game... if I ever get to go hunting again..

Are those High Standards?

By smaller frame AR, do you mean short action chambered for 308?

The 308/7.62 by 51mm sounds ideal, why didn't the military go with the 6.5 Grendel to upgrade the 5.56?/?
Cheap brass seekers want to know?!

Mr. Alexander? I don't know this person
